.To all whom, it may concern:

Be it known that I, JACOB BowMAN .Mo- KENNAN, a citizen of the United States, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented certain new and useful Improvements in Furnace-Valves, of which the followingis a specification.

My invention relates to improvements in Water-sealed valves for regenerative fur-` naces and the like; and itsobject is to provide an opening and closing valve and a reversing valve, which latter is .in effect a diverting flue, and which valves sliall avoid the defects of valves of the mushroom, butterfly and other types.

The valve may be either a sim le'opening and closing valve controlling on y two flue terminals; or it may be a three-way reversing valve; that is, a valve lcontrolling three iue terminals, and either form may be duplicated either side-by-'side or end-to-end but in all cases the valve proper or hood, is entirely uninclosed .above and allliue terminals .controlled by the valve or hoods'rise through the water-pan, rendering hoods, pan and o erating mechanism easy of access.v So iger as I am aware, valves heretofore used `have been either arranged to raise and lower or to reciprocate within a closed valve chamber or they have been a movable part of such valve chamber or they have been of the rotative type. I believe that,reciprocating water-sealed valves, having sup )lemental sealing hoods are new and l intend to claimv the same broadly.

My improved valves are particularly adapted for use with the ilue systexns, for regenerative furnaces, ofthe types described in my copending application Serial N o. 316,773. In the accompanying drawings: Figure l is a longitudinal sectionof a simple opening and closing water-sealed valve constructed according to my invention; Fig. 2 is a plan of the water-pan for the same; llig. 3 is a longitudinal section of `a form of a simple watersealed reversingevalve or diverting llue'; Fig. 4 is aplan of the water-pan for same; Fig. 5 is a transverse section of a double valve which may be an opening and closing valve of the'type shown in Fig. 1,. or a reversing valve of the type shown in Fig. 3; Fig. 6, is a plan of the water pan for same when used as a reversing valveg'Fig. 7 is a plan similar to Fig. 6, adapted to a duplex reversing valve, the o1' posite positions of the independent valves being shown in dotted lines Fig. 8 is a longitudinal section; Fig. 9 a plan of water-pan of a tandem opening and closing valve, Fig.. l() is a longitudinal section and Fig. 11 a plan of pan of a tandem reversing valve; Fig. l2 is a longitudinal section of a modified form of a simple reversing valve `hereinafter referred to Fig. 13 is a longitudinal section and Fig. 14 a plan of a water-cooled and. water-sealed opening and closing valve 5 Fig. l5 a longitudinal section and Fig.' 16 a plan oi' a similar water-cooled and water-sealed sim `)le reversing valve.

Like nuinerais refer L to similar parts throughout the several iigures.

l represents in a general way the valve hood integral with either or both ends oi'` which are supplemental hoods 2.

3, 3, (Fig. i) represent truck wheels supporting the hood and running upon tracks 4.

5,5, are suitably located (.lepressions in the tracks 4, to permit one pair ol truck wheels to fall and lower the valve to sealing position after it has cleared the ii'iterior ribs ol the water-pan which Is'urround. the llues. By this construction, lie valve may be reciproeated without lii'tin; the entire valve.

v is a suitable rrlractory lining for the hoods.

7 is the water-pan, provided with a suit- ,able supply pipe 8 and discharge. pipe t), to

maintain the water seal ata practically constant level.

10, l0, represent substantially vertical and parallel extensions of the llucs to be controlled by the various forms ol valves, and

such f'lues may be air, gas, or draitllues, ac

cording t0 thi` location of the valveand the 'direction oi' the current therethrough, as will be readily understood.

11, (Fig. l) represents diagrammatically suitable actuating means l'or the valve., which i means may comprise a lluid pressure. cylinder having a piston and a piston-rod removably connceted to the valve-hood in. any de` .sired manner so that the calves may be readily detached for repairs. lt will be u-nderstood that the other l'orms of valves shown may be supported and reciprocated in like manner and that all forms are readily removable from their water-pans.

12, (Fig. 1) represents a vent for thc supplemental hood which may be pro vided when the ilue sealed by said hood has a stack connection. Undersueh conditions, where the valve 1s in the position of Fig. 6, the vent acts to equalize the internal and external `pun n'hieli surrounds the rertieiil .fluid presiures and. to prevent. the ten'iporiiry rise of level of liquid in the. witter-pun which' ln Fig. 1, the calvo shown-in open po- 'sition that eonneetinir the lues it), lll to connect the air or ,Qns suppl)v flue with the i'eggeueizitor Chamber, or the hitter with the stiiek, is the ense nizzyfbe.
